[Factors related to a suboptimal bowel preparation for colonoscopy].

Introduction: Colonoscopy is the standard method for the evaluation of the colon. A suitable intestinal cleaning is critical for the effectiveness and security of the procedure, but unfortunately there is a high proportion of suboptimal bowel preparation.

Objective: To identify factors related to suboptimal bowel preparation.

[Quality indicators for colonoscopy in the Peruvian Japanese Policlinic: linked factors].

Introduction: Colonoscopy is the gold standard for the diagnosis of diseases of the colon and rectum and the primary prevention test for colon cancer. The main indicators of quality in colonoscopy are the rate of complete colonoscopy and the rate of detected adenomas.

Objectives: We aimed to know the rates of cecal intubation and detection of adenomas and to identify factors related to these two quality indicators in colonoscopies performed in the Peruvian Japanese Policlinic during 2007.

Variation in the prevalence of gastric cancer in Perú.

Most cases of gastric cancers occur in non-industrialized countries but there is scarce information about the epidemiology of this illness in these countries. Our study examined whether there was a variation in the prevalence of gastric cancer in Lima, Perú over the last 2 decades. Subjects older than 29 years of age were included.

Decrease in prevalence of peptic ulcer and gastric adenocarcinoma at the Policlínico Peruano Japones, Lima, Peru, between the years 1985 and 2002. Analysis of 31,446 patients.

Aim: To determine the prevalence of peptic ulcer and gastric adenocarcinoma in a population of middle and high socio-economic status in Lima, Peru, between 1985 and 2002.

Material And Methods: The prevalence of gastroduodenal ulcer and gastric adenocarcinoma was determined after studying by esophagogastroduodenoscopy 31,446 patients at the Policlínico Peruano Japonds (PPJ) between 1985 and 2002. All patients had chronic upper gastrointestinal symptoms and had endoscopically proven diagnosis of active peptic ulcer or histological diagnosis of gastric adenocarcinoma.

[Comparison of the prevalence of Helicobacter pylori stomach infection in Peruvian and Japanese population].

Objective: To compare the prevalence of Helicobacter pylori infection in native Peruvians and Japaneses residing in Peru.

Methods: Prospective study carried out at "Policlinico Peruano-Japonés" (Lima-Perú). We included Peruvians and Japaneses residing in Peru with chronic symptoms of the upper gastrointestinal tract.

[Epidemiologic study of Helicobacter pylori infection in Perú].

We present the results of our investigations in the epidemiology of H. pylori infection in Peru during the last two decades. The prevalence of Helicobacter pylori infection in Lima is decreasing in people of middle and high socioeconomic status and continues stationary in people of low socioeconomic status.

[Omeprazole, amoxicillin and clarithromycin in the treatment of helicobacterpylori, in 7 and 10-day regimens].

Aim: The most accepted treatment for infection by Helicobacter pylori is the proton pump inhibitor based therapy with two antibiotics. However, there is no consensus regarding the duration. The purpose here was to compare eradication percentages in the omeprazole+amoxicillin+clarithromycin regimen administered during 7 days versus 10 days and confront the results with a previous 14-day* experience in Peru.

[CONTRIBUTION STUDY TO THE EPIDEMIOLOGY OF HELICOBACTERPYLORI IN PERU: ANALYSIS OF 3005 CASES].

Compiling our observations from the last 15 years in regard to the epidemiology of Helicobacter pylori in Perú, we have analized 3005 cases. Studying and comparing the rates of infection among japanese inmigrants living in Perú for more than 10 years, niseis, japanese visitors and peruvians, we found similar rates. According to these results it seems that at least in japaneses there is not any genetic predisposition to acquire the infection.
